unclear tcl error

alb · Apr 28, 2014

Hi everyone,

I must admit that I'm pretty new to tcl scripting so this error might be
plain stupid but I've failed to understand it so far.

I have a makefile (taken from the openrisc repo on opencores.org and
adapted to my needs) which has a set of rules to control the whole place
and route flow, from compilation to bitstream generation. Among these
rules there's one to extract timing reports that goes like this:

# Generate reports
$(TCL_SCRIPT_REPORT):
TCL_FILE=$@ $(MAKE) tcl-common
$(Q)echo "run_designer \"Generating timing reports\" \" " >> $@
$(Q)echo " open_design $$""proj_name.adb " >> $@
TCL_FILE=$@ $(MAKE) dump-actel-report-project-tcl
$(Q)echo "\"">> $@

The tcl-common provides a set of common parameters to each step of the
flow and works fine, while the dump-actel-report-project-tcl looks like
this:

# TCL commands to generate timing reports of project
dump-actel-report-project-tcl:
$(Q)echo " report " \\ >> $(TCL_FILE)
$(Q)echo " -type timing " \\ >> $(TCL_FILE)
$(Q)echo " -analysis max " \\ >> $(TCL_FILE)
$(Q)echo " -print_summary yes " \\ >> $(TCL_FILE)
$(Q)echo " -use_slack_threshold no " \\ >> $(TCL_FILE)

$(Q)echo " -max_paths 100 " \\ >> $(TCL_FILE)
$(Q)echo " -max_expanded_paths 0 " \\ >> $(TCL_FILE)
$(Q)echo " "$(DESIGN_NAME)"-timmaxdly.rpt " >> $(TCL_FILE)
$(Q)echo " report " \\ >> $(TCL_FILE)
$(Q)echo " -type timing_violations " \\ >> $(TCL_FILE)
$(Q)echo " -analysis min " \\ >> $(TCL_FILE)
$(Q)echo " -use_slack_threshold no " \\ >> $(TCL_FILE)
$(Q)echo " -limit_max_paths yes " \\ >> $(TCL_FILE)
$(Q)echo " -max_paths 100 " \\ >> $(TCL_FILE)
$(Q)echo " -max_expanded_paths 0 " \\ >> $(TCL_FILE)
$(Q)echo " "$(DESIGN_NAME)"-timmindly.rpt " >> $(TCL_FILE)

When I run the 'make report' I get the following error at the end:

debian@debianlace_route$ make report

Hi,

I think Make assumes that an exit code of 0 means success, and anything else implies failure. That seems to be why there is an error. From your log, it doesn't look like the Tcl script exited with an error.

From your log, it doesn't look like the Tcl script exited with an
error.

From 'make' manual: Errors in Recipes.
After each shell invocation returns, make looks at its exit status. If
the shell completed successfully (the exit status is zero), the next
line in the recipe is executed in a new shell; after the last line is
finished, the rule is finished.

If you look carefully to the code (re-posted here for convenience) I
posted it is pretty clear the tcl script has flagged an error, but it
doesn't seem to me clear what type of error it might be:

while executing
"exec designer SCRIPT:designer.tcl LOGFILE:report.log"
(procedure "run_designer" line 6)
invoked from within
"run_designer "Generating timing reports" "
open_design $proj_name.adb
report \
-type timing \
-analysis max \
-print_summary yes \
-..."
(file "report.tcl" line 18)
Command exited with non-zero status 1

Still wandering in the dark...
